Hi.
I was wondering how I could create a similar effect of this:

It is like a group of orange bars forming around a circular logo, look at the video and it will make more sense.

Trapcode Particular or Form, most likely. you can generate similar effectrs however by using Displacement effects such as Turbulent Displace. Use masks in combination with the Stroke effect, animate the starts and ends. Then apply Al lthe other effects and animate their parameters to get that smokey look. You can further refine this by adding CC Force Motionblur. Of course feel free to throw any other effect like Glow and Box Blur into the equation.
